Photosynthesis:
* Input: Photosynthesis uses carbon dioxide (CO2) and water (H2O) as inputs.
* Output: The primary output of photosynthesis is glucose, a simple sugar (carbohydrate). This glucose is the fuel for cellular respiration.
* Process: Photosynthesis captures light energy from the sun and uses it to convert CO2 and H2O into glucose. This process stores energy in the chemical bonds of the glucose molecule.
Cellular Respiration:
* Input: The primary input for cellular respiration is glucose (the carbohydrate produced in photosynthesis).
* Output: Cellular respiration releases energy from glucose and produces:
* ATP (adenosine triphosphate), the energy currency of cells.
* Carbon dioxide (CO2), which is released back into the atmosphere.
* Water (H2O), a byproduct of the process.
* Process: Cellular respiration breaks down glucose in a series of steps to release its stored energy. This energy is used to power various cellular processes.
In summary:
* Photosynthesis creates carbohydrates (glucose) to store energy.
* Cellular respiration breaks down carbohydrates (glucose) to release energy.
This cycle of energy production and utilization is essential for all living organisms.
